use of Timer1 and portA interrupts together

[Alexey]

Hi Darrel,

Thank you very much for help!

Do I understand correctly that at other than 4 MHz frequency oscillator may affect interrupts? I mean is it affected at 8 MHz or you meant 32 kHz oscillator?

Best regards,


Alexey

The OSC frequency doesn't directly affect or interfere with interrupts.

Your original program was set up for 4Mhz, so any change in OSC frequency could affect the way your program handles the interrupts.

The main thing is selecting the correct oscillator mode (XT, HS) for your crystal.
